WILMINGTON — New Castle County executives are reminding residents that their annual residential sewer fee payments are due Monday.

Payments can be made online, via the mail or in person.

To pay online using Paymentus, residents can go here. To pay over the phone, residents should call (877) 225-7351.

For both of these methods, taxpayers can use credit cards, debit cards or e-check services without a fee.

While the New Castle County Government Center is not open, there is a dropbox in front of the office where people can leave their payments in person. This box will be available until March 5.

To avoid late fees, residents need to make sure the county receives their payment before Monday.

For any questions or concerns, taxpayers should reach the county’s Treasury Department at 395-5340 or treasury@newcastlede.gov.
